Abstract: An improved method and apparatus is provided to conl the moisture content of pulp which is discharged from a press. During operation of the press (14) slurry containing the pulp enters the press (14) and engages a screw (28) which is rotated to feed the pulp upwardly in the press (14). As the wet pulp moves upwardly, water is removed from the pulp. In order to further reduce the moisture content of the pulp, a restrictor member or cone (60) in the press outlet (42) is effective to compress the pulp against helical flighting (38) of the screw (28). In order to maintain the moisture content ofthe discharged pulp substantially constant with variations in wet pulp consistency and to prevent overloading of the press drive motor (32) the restrictor cone (60) is movable axially along the screw drive shaft (34) to vary the extent to which it restricts the press outlet (42). The restrictor cone (60) is moved along the screw drive shaft (34) under the influence of forces applied against the outer surface (64) of the cone (60) by the wet pulp. This movement of the cone (60) adjusts the extent to which the outlet (42) from the press is restricted and the extent to which the wet pulp is compressed with variations in the consistency of the wet pulp.

Abstract: A light box is for supporting a stack of essentially transparent sheets including photo material which is insensitive to daylight and sensitive to shortwave light, and a record carrier film having transparent regions in the form of the characters or other representations to be produced and an opaque background to shortwave light. The illumination by the light box facilitates positioning of the record carrier film relatively to the photo material, and a grid can be a further help in positioning. A flash device having an aperture, the size of which corresponds to the size of the character or other representation, is for producing the shortwave light to blacken the photo material corresponding to the selected record on the record carrier film.

Abstract: Apparatus for the treatment of ocular misalignment by electrical stimulation of ocular recti. A body implantable unit develops an electrical stimulation signal and delivers that signal to an ocular rectus without restricting its contraction, In a preferred embodiment, the implanted unit includes a receiving member 15 which cooperates with an external transmitting unit, the external transmitting unit establishing the stimulation signal parameters. The receiving member 15 is connected to a lead 16 carrying an electrode 17 which is shaped so as to contact the ocular rectus 12 without interfering with its contraction. Preferably, the stimulation signal is a periodically interrupted train of pulses, the repetition rate of the stimulation signal pulses being within the range of 50 to 100 pulses per minute. The interruption of the pulse train results in a stochastic stimulation with the pulse train being delivered for approximately 1 to 5 seconds with the interval between stimulation signals being from approximately 5 to 25 seconds. The pulse amplitude may be selectively established in the range from about 0.8 to 15 volts with the pulses having a pulse width of approximately 0.22 milliseconds. During stimulation, a divergence movement is attained to correct the ocular misalignment while chronic stimulation results in a histological and an atomical change in the stimulated rectus which also tends to overcome the ocular misalignment.
